    writer’s grandparents feel that a penny is worth bending over and picking it off of the ground every time they come across one. Benjamin Franklin once said‚ “A penny saved is a penny earned” (BrainyQuote 2016). If you pick up every penny that you find‚ they eventually will add up. There used to be candy stores that had penny candy but nowadays‚ there is nothing that actually costs a penny. Many people look down at the ground‚ see a penny and leave it there. For them‚ the penny is not worth any effort to

    Pennies don’t put in their two cents for their place as a part of American currency. It’s not like they’re particularly useful. Almost nobody picks them up unless it’s in the hope that the face of the long-deceased Abraham Lincoln might bring them good fortune of some odd sort. Thieves don’t scrounge around people’s pockets for pennies‚ and then have the person call the police for their missing penny. When most people say that they want to keep the penny‚ most of the time it will simply be an infantile

    Should the U.S. Government Keep the Penny in Circulation? Annoying cashiers was something my siblings and I did quite unintentionally as kids.
